To identify apraxia of speech (AOS), which of the following must be present?

• A. Articulatory abnormalities
• B. Both articulatory and prosodic abnormalities
• C. Prosodic abnormalities
• D. No abnormalities

Answer: (B)

To accurately identify apraxia of speech (AOS), both articulatory and prosodic abnormalities must be present. AOS is characterized primarily by difficulty in planning and programming the movements necessary for speech, which manifests as distortions or substitutions in speech sound production (articulatory abnormalities). This difficulty can affect the precision of sounds as well as the overall clarity of speech. In addition to articulatory issues, prosodic abnormalities may also occur, which can affect the rhythm, stress patterns, and intonation of speech. These prosodic features can be markedly disrupted in individuals with AOS, leading to an unnatural flow of speech. Therefore, the presence of both types of abnormalities helps distinguish AOS from other speech disorders, such as dysarthria or phonological disorders, where the specific patterns of errors may differ. Thus, recognizing that both articulatory and prosodic abnormalities are integral to identifying AOS underscores the complexity of the disorder and the necessity for comprehensive evaluation in those suspected of having this condition.
